Prefab fireplace repair in Princeton/Silver Star

When a cracked panel needs replacing

Makers set their own limits for when a cracked refractory panel should be replaced, and those limits live in the owner's manual for each model. A panel that has lost pieces, crumbles at the edges or leaves steel showing behind it is past any reasonable limit.

We read your model's guidance, look at every panel and tell you which ones need replacement now and which can be watched. The estimate names each panel by its position and its part number.

• Pieces missing from the panel
• Crumbling edges
• Steel visible behind the panel
• Cracks wider than the manual allows

The chimney is part of the fireplace's listing

A factory-built fireplace is tested with a specific chimney. Section R1005.4 says chimneys for use with factory-built fireplaces shall comply with UL 127, the same standard as the fireplace, and R1005.1 has factory-built chimneys listed and labeled, then installed and finished at the top as their maker directs.

That makes the metal chimney a matched part of the system. Repairs to pipe sections, supports or the top of the chimney use the components the fireplace's manual names.

A fireplace for supplemental heat

A prefab fireplace is built to add warmth to a room. One maker states that its factory-built fireplace is not intended as a substitute for a furnace to heat an entire home, and is meant for supplemental heat only. Long, hot fires meant to warm the whole house are one path to overfiring.

A sensible fire sized to the firebox protects the panels and the metal. We share the manual's guidance when we hand back a repaired fireplace.

A cracked firebox floor panel

The floor panels of a factory-built firebox carry the grate, the fire and the ash, and they take the knocks from logs and tools. Cracks there often show before the side panels wear.

One maker divides the floor into bottom rear and bottom front panels, so a cracked front piece can sometimes be replaced alone. We check both before ordering.

• Bottom front panel
• Bottom rear panel
• Grate position over the floor
• Retainers along the edges
